First attempt to prelink all LO libraries into 1 static library.

With all libraries directly linking to the swift module, link time
is about 12 minutes.

Experiments let to be believe this can be reduced to 1-2 minutes
by doing prelinking, which will solve all symbols between the
libraries.

Because work will continue on the swift module, while the LoKit
is a pretty stable interface, this will save much developer time
